About Happi 20 Tablet

Happi 20 Tablet belongs to a group of antiulcer medicines called proton pump inhibitors used to treat duodenal ulcers, gastro-oesophageal reflux disease (reflux of gastric contents into the oesophagus), heartburn, erosive oesophagitis (acid-related damage to the lining of the oesophagus), infections caused by Helicobacter pylori when given along with an antibiotic, and Zollinger-Ellison syndrome.

Happi 20 Tablet contains 'Rabeprazole' that works by blocking the action of the enzyme known as gastric proton pump which is responsible for the production of acid. This helps in reducing the amount of acid produced, heals the ulcers and prevents the formation of new ulcers.

Disease/Condition Glossary

Acidity: The stomach is usually protected from the acid by a mucous layer. In some cases, due to excess acid production, the mucous layer gets eroded, which leads to complications like acidity, GERD, heartburn, peptic ulcer, and Zollinger Ellison syndrome.

Gastroesophageal reflux disease (GERD): It is a condition that occurs when stomach acid frequently flows back into the food pipe (oesophagus). This backflow (acid reflux) irritates the food pipe and causes heartburn.

Duodenal ulcer: It is a painful condition followed by the development of sores or ulcers in the duodenum or stomach lining (first part of the small intestine, i.e., the duodenum).

Zollinger Ellison syndrome: It is a rare condition in which a gastrin-secreting tumour of the pancreas causes excessive acid production leading to peptic ulcers.
